Abstract (en)

[origin: EP3988639A1] Damage to cells is suppressed in a cell recovery method that does not require a centrifuge. When recovering cells which are cultured in at least one container containing a liquid medium and adhere to an inner surface of the container, a medium discharge step (step S 11) of discharging the medium from the container, a peeling liquid supply step (step S12) of, after the medium is discharged, supplying a peeling liquid for peeling the cells from the inner surface of the container to the container, a peeling liquid discharge step (step S14) of discharging the peeling liquid from the container before the cells are completely peeled from the inner surface of the container, a waiting step (step S15) of, after the peeling liquid is discharged, waiting until the cells are peeled by action of a residual peeling liquid, and a recovery liquid supply step (step S16) of, after the waiting step is completed, supplying a recovery liquid for recovering the cells to the container are performed.
